The 49ers bolstered their front office by hiring former NFL player Ran Carthon as their Director of Pro Personnel, the team announced Friday.

Carthon, 36, who held the same front-office title for the Rams the past five seasons, becomes the third San Francisco personnel executive added this offseason by new general manager John Lynch. He replaces Mike Williams, who was let go by Lynch two weeks ago.

“We want to welcome Ran Carthon and his family to the 49ers,” Lynch said in a statement. “Ran has a clear vision for how he plans to run our pro personnel department, and was excited about the opportunity to blend his approach with ours. Having previously directed his own pro department, we expect Ran to hit the ground running and help us build the strongest roster possible.”

Carthon was one of four Rams scouts who were fired just three weeks before the NFL draft. Before joining the Rams, Carthon worked five years as a scout for the Atlanta Falcons under current Rams GM Les Snead.

Carthon, whose father, Maurice, was an 8-year NFL running back with the New York Giants and Indianapolis Colts, also played for four NFL teams. After leaving the University of Florida in 2003, the younger Carthon signed with the Colts and scored a pair of touchdowns in nine games in 2004. He also had brief stays with Green Bay, Seattle and Detroit from 2005-06.

Carthon’s role for the 49ers will include assisting with free agency and overseeing the evaluations of NFL players.

It was a momentous weekend, and it was shaped primarily by someone who wasn’t there. NFL teams may not have signed him to play quarterback this season, but they could not keep Kaepernick off the field.

Compounding the 49ers’ 0-3 start is that their past two defeats have come against NFC West rivals. Up next is another division opponent Sunday, when the 49ers visit the Arizona Cardinals.
